OK, let's start from the top.
what we know:
- We see it is a R1200R.
- We know it now has 78299.0 km on the odo
- We also see that the Fault codes are NOT present... now that could mean that they are intermittent OR that the problem has been addressed/fixed but the fault codes never cleared....
Now from the Fault code history we see the following:
- the fault occurred at 78176.0km - that is 123 km ago
- we also see that it occurred at 1440rpm
- we also see that the logistic counter is at 27
The logistic counter starts at 40 for most codes and then decrements every "cycle" that the fault is not present... Now what exactly a "cycle" is, is unknown... and I suspect it might differ from fault code to fault code... for some it might be ignition cycles for others it might be engine reaching operating temperature etc... (naturally it will reset back to 40 if the fault occurs again)
In either case, I suspect that fault was not repaired... BUT, that still does not mean that something needs to be done...
Next we need to consider the context... this is a knock sensor... it measures vibration.. it might have gotten a hard knock from another source (someone banged a hammer against the engine - I hope not), or the sensor might even be loose (normally tightened to the engine with a bolt - naturally if it is loos, it will loose it's ability to "feel" the mechanical vibrations...)
On the other hand, it could be a loose or dirty connector... or poor connection...
Check all of the above (mounting, connections - maybe even clean the connections ...then reset the code... and check it frequently...
best
